Description

Compositions and formulations comprising cabazitaxel and human serum albumin
The application is a divisional application of patent application with application number 201780006603.4 and application name of 'composition and preparation containing cabazitaxel and human serum albumin' of 2017, 01 and 12 days.
Priority claim
The application claims the benefit of U.S. provisional application Ser. No. 62/420,986, filed 11/2016, and U.S. provisional application Ser. No. 62/279,074, filed 1/15/2016. The entire contents of the foregoing application are hereby incorporated by reference.
Technical Field
The present disclosure relates to complexes and compositions for treating proliferative diseases.
Background
Many drugs for parenteral use are insoluble in water and therefore are formulated with solubilizers, surfactants, solvents and/or emulsifiers that are irritating, allergic or toxic when administered to a patient. See, e.g., briggs et al ANESTHESIS, 1099 (1982); and Waugh et al, am.J.Hosp.Pharmacts, 48,1520 (1991)). In addition, many of these drugs, especially those administered intravenously, cause undesirable side effects such as venous irritation, phlebitis, burning and pain upon injection, venous thrombosis, extravasation, and other administration-related side effects. In addition, the free drug present in the formulation generally induces pain or irritation after administration.
Taxanes play an important role in the treatment of various solid tumors. Cabazitaxel (trade name)) Is a semisynthetic taxane derivative. It was developed by Sanofi-Aventis and approved by the United states FDA for the treatment of hormone refractory prostate cancer at month 6 and 17 of 2010. The combination of cabazitaxel with prednisone is a therapeutic option for hormone refractory prostate cancer following cabazitaxel-based therapy. JEVTANA is supplied as a kit comprising (a) JEVTANA injection containing 60mg of cabazitaxel in 1.5mL of polysorbate 80; and (b) a diluent comprising about 5.7mL 13% (W/W) ethanol. Prior to administration, JEVTANA injections must first be mixed with a diluent, the amount of cabazitaxel diluted to 10mg/mL, and then further diluted with 0.9% sodium chloride solution or 5% dextrose solution for infusion. See JEVTANA for prescription information.
Other taxane compounds include cabazitaxel asSquamous cell carcinoma marketed and approved by the FDA for breast cancer, non-small cell lung cancer, hormone refractory prostate cancer, gastric adenocarcinoma, and head and neck cancer. Commercially available cabazitaxel/>Is formulated with a highly concentrated solution containing 40mg cabazitaxel and 1040mg polysorbate 80 per mL. See TAXOTERE prescription information.
The presence of polysorbate 80 in JEVTANA and TAXOTERE can lead to serious side effects. Cabazitaxel administration has been reported to be associated with unpredictable (acute) hypersensitivity and the occurrence of cumulative fluid retention. See, e.g., trudeau ME et al, J Clin Oncol 1996;14:422-8; piccart MJ et al, J NATL CANCER INST 1995;87:676-81; bruno R et al, J Clin Oncol 1998;16:187-96. These side effects are due in part to the presence of polysorbate 80.
To reduce the side effects induced by polysorbate 80, patients may be treated with dexamethasone prior to each JEVTANA dose. Dexamethasone is a steroid that inhibits the immune response of patients, which may be particularly detrimental in chemotherapy cancer patients whose immunity may have been compromised by the destruction of healthy cells by chemotherapy treatment. Thus, these patients may be prone to bacterial and fungal infections. Furthermore, despite pre-administration of dexamethasone, patients may still report hypersensitivity side effects from taxane treatment. Because of these side effects, the patient may stop taxane treatment, skip the dose, or continue further treatment with a reduced dose.
Thus, new formulations of cabazitaxel or other taxane compounds are needed to avoid these side effects, pre-medication requirements, and patient non-compliance issues associated with currently marketed formulations.

By controlling the pH and ethanol content, semi-purified fractions of plasma proteins can be produced. The last protein precipitated in the Cohn process is native human serum albumin. After precipitation, a wet paste of crude natural human serum albumin is obtained. Subsequent bioprocessing steps (purification, filtration, pasteurization, etc.) can be used to produce purified, stabilized forms of natural human serum albumin for commercial use (Lin JJ et al Pharmaceutical Research, 2000; 17:391-6). Recombinant human serum albumin is a highly purified animal, virus and prion free product that is structurally identical to natural human serum albumin as a substitute for natural human serum albumin (Bosse D et al J.Clin.Pharmacol.2005; 45:57-67). Recombinant human serum albumin has been produced by a variety of prokaryotic and eukaryotic hosts (Chen Z et al Biochimica et Biophysica Acta 2013; 1830:5515-5525). Fatty acid-free human serum albumin can be prepared by treating human serum albumin with charcoal at low pH. Likewise, treatment of human serum albumin with charcoal at low pH can be used to remove fatty acids from human serum albumin (Chen RF, J.Biol.Chem.1967; 242:173-181).
Human Serum Albumin (HSA) is a highly soluble globular protein of Mr 65K and consists of 585 amino acids. HSA is the most abundant protein in plasma and accounts for 70% to 80% of the colloid osmotic pressure of human plasma. The amino acid sequence of HSA contains a total of 17 disulfide bridges, one free thiol (Cys 34) and a single tryptophan (Trp 214). Intravenous HSA solutions have been indicated for the prevention and treatment of hypovolemic shock (see, e.g., tunelis, JAMA,237,355-360,460-463, (1977)) and Houser et al, surgery, gynecology and Obstetrics,150,811-816 (1980)) and in combination with blood changes for the treatment of neonatal hyperbilirubinemia (see, e.g., finlayson, SEMINARS IN Thrombosis and Hemostasis,6,85-120, (1980)).
Human Serum Albumin (HSA) has multiple hydrophobic binding sites (7 in total for medium and long chain fatty acids (endogenous ligands for HSA)) and binds to a diverse group of drugs, in particular neutral and negatively charged hydrophobic compounds (Goodman et al The Pharmacological Basis of Therapeutics, 9 th edition, mcGraw-Hill New York (1996)). Two high affinity binding sites have been proposed in subdomains IIA and IIIA of HSA, which are highly elongated hydrophobic pockets with charged lysine and arginine residues near the surface that serve as the attachment points for polar ligand features (see, e.g., fehske et al ,Biochem.Pharmcol,30,687-92(1981),Vorum,Dan.Med.Bull,46,379-99(1999);Kragh-Hansen,Dan.Med Bull,1441,131-40(1990);Curry, nat. Struct. Biol,5,827-35 (1998); sugio et al protein. Eng.,12,439-46 (1999); he et al Nature,358,209-15 (1992); and Carter et al, adv. Protein. Chem.,45,153-203 (1994)).
In some embodiments, the human serum albumin is a native human serum albumin. In some embodiments, the human serum albumin is recombinant human serum albumin. In some embodiments, the human serum albumin is a fatty acid free human serum albumin. In some embodiments, the human serum albumin is substantially free of fatty acids. In some embodiments, the human serum albumin contains no more than 2 moles of fatty acids that bind to 1 mole of human serum albumin. In some embodiments, the human serum albumin contains no more than 1 mole of fatty acids that bind to 1 mole of human serum albumin. In some embodiments, the human serum albumin contains no more than 0.5 mole of fatty acids that bind to 1 mole of human serum albumin. In some embodiments, the human serum albumin contains no more than 0.1 mole of fatty acids that bind to 1 mole of human serum albumin. In some embodiments, the human serum albumin contains no more than 0.05 moles of fatty acids bound to 1 mole of human serum albumin. In some embodiments, the human serum albumin contains no more than 0.01 mole of fatty acids that bind to 1 mole of human serum albumin. In some embodiments, the human serum albumin contains no more than 0.001 mole of fatty acids that bind to 1 mole of human serum albumin. In some embodiments, the human serum albumin contains no more than 0.0005 moles of fatty acids bound to 1 mole of human serum albumin. In some embodiments, the human serum albumin contains no more than 0.0001 moles of fatty acids bound to 1 mole of human serum albumin.
As used herein, the term "non-covalently bound complex" refers to a complex in which the bonds between the components of the complex are non-covalent (e.g., weak bonds such as hydrogen bonds, electrostatic interactions, pi-effects, hydrophobic interactions, and van der waals forces). Furthermore, human Serum Albumin (HSA) has multiple hydrophobic binding sites (7 in total for medium and long chain fatty acids (endogenous ligands for HSA)) and binds to a diverse group of drugs, in particular neutral and negatively charged hydrophobic compounds (Goodman et al The Pharmacological Basis of Therapeutics, 9 th edition, mcGraw-Hill New York (1996)). In addition, after the drug molecule binds to HSA, the drug molecule and HSA form a non-covalently bound drug and protein complex through the binding site of HSA. This concept is generally known to those of ordinary skill in the art to which this disclosure pertains. One example of a non-covalently bound complex is a non-covalently bound complex of HSA and a fatty acid, wherein the fatty acid binds to HSA through multiple binding sites of HSA.
As used herein, the term "stable" refers to non-covalently bound complexes that are not readily dissociated and aggregated into their separate portions, e.g., are not readily dissociated and aggregated over a period of 6 hours, 12 hours, 24 hours, or 3 days. For example, a solution comprising a stable non-covalently bound complex will typically appear transparent, while a solution comprising an unstable non-covalently bound complex will appear translucent or cloudy. Furthermore, one of ordinary skill in the art will appreciate that after a period of time, the stabilized non-covalently bound complex may dissociate and aggregate into its individual moieties. Thus, solutions comprising stable non-covalently bound complexes may become translucent or cloudy after a period of time (e.g., 6 hours, 12 hours, 24 hours, or 3 days).
In vitro, the binding rate of cabazitaxel to human serum albumin is 89% to 92% and is not saturable to 50,000ng/mL, which covers the maximum concentration observed in clinical trials. Cabazitaxel binds mainly to human serum albumin (82%). See JEVTANA for prescription information.
As used herein, the term "substantially free of fatty acids" refers to proteins (e.g., serum albumin) that contain less than about 0.02 wt.% fatty acids. For example, human serum albumin that is substantially free of fatty acids may contain less than 0.02% fatty acids by weight.
